Space-borne Sub-THz ISAR System for Objects with Translational Motion

The exploitation of sub-terahertz technology (200 GHz-700 GHz) is proposed for imaging and the recognition of an object's state from a space-based sensor using inverse synthetic aperture radar, benefiting from wide bandwidth and enhanced sensitivity to surface texture of signals in this band. An initial technical analysis of the system is presented with the calculation of expected resolutions and of the power budget. Initial experimental results from measurements in a scaled environment are presented.
